Take the Kado Wallet, supposedly the world’s thinnest charger. At roughly the thickness of three credit cards stacked on top of each other, the charger really does fit in my bi-fold wallet without adding any serious bulk.

It comes with a 2-foot long retractable cord (micro USB, Lightning or USB-C), and the foldable prongs on the top half are interchangeable, so you can attach the proper plugs for different regions.

And that’s it. It’s so simple and small, and I really want one.

Sadly, I can’t go out and buy a Kado Wallet just yet. The company behind it, which also goes by Kado (that’s a play on “card,” in case you didn’t figure it out), says it’s planning to launch the product on Kickstarter in the near future for about $50.

$50 for a thin charger is pretty steep, but if that’s the price to get wallet-friendly gadgets, I’ll pony up.

Kado’s other slim-charger-you-never-knew-you-wanted is the Kado Sleeve. It’s a 70-watt laptop charger that’s almost as thin as a pencil and the size of a smartphone. It’s also got two full-sized USB ports for charging your other devices, like smartphones and tablets.

Kado says the Kado Sleeve is designed to fit inside of your laptop sleeve thanks to its foldable design.

The prototype Kado Sleeve I got to see at Mobile World Congress was still rough around the edges, but you get the idea. It’ll come with a 6.5-foot long cable and various charging tips to fit different laptops.

The Kado Sleeve will also launch on Kickstarter sometime in the near future. I’m told it will cost about $99.

Look at how small the Kado Sleeve is compared to standard laptop chargers (top).
